#observability

Observability is the ability to monitor and measure the state of a system, including its performance, health, and behavior. It is an important part of software development in the JavaScript domain, as it allows developers to detect problems with their code and be able to quickly identify and fix them. Observability also allows for debugging and analyzing applications, and helps developers understand how their code is behaving in real-time.

Grafana uses React to power its open source platform, leveraging its vast ecosystem, improved performance, and community contributions. The choice of state management tool depends on the team's problem space. React Hooks have posed challenges but have also been a powerful tool for developers. The new Scenes library simplifies development and reduces the learning curve. Despite challenges, React remains a powerful tool for complex frontends, and Grafana will continue to use it.

Observability with diagnostics_channel and AsyncLocalStorage

Stephen Belanger

Node.js core contributor and founder of the diagnostics working group.

Observability with Diagnostics Channel and async local storage allows for high-performance event tracking and propagation of values through calls, callbacks, and promise continuations. Tracing involves five events and separate channels for each event, capturing errors and return values. The span object in async local storage stores data about the current execution and is reported to the tracer when the end is triggered.

Getting Started with Open Source Observability

Connor Lindsey

Grafana Labs

Observability is a crucial tool for engineers to ship reliable websites and have a good developer experience. Metrics, logs, and traces are fundamental data types for achieving observability. OpenTelemetry is an open source standard for observability data, and instrumentation can be done manually or automatically. Data collection and transportation can be handled by packages built by the OpenTelemetry community, and the collector running can add security benefits. Grafana is used for data visualization, and it allows for analyzing web performance, exceptions, and traces. Traces capture user interactions and provide insights into user behavior and error occurrences. Leveraging these tools allows for gaining insights into various parts of the system and improving engineering goals.

Observability for Microfrontends

Konstantinos Leimonis

Staff Software Engineer @ DAZN

Microfrontends follow the microservices paradigm and observability is crucial for debugging runtime production issues. Error boundaries and tracking errors help identify and resolve issues. Automation of alerts improves incident response. Observability can help minimize the time it takes to understand and resolve production issues. Catching errors from the client and implementing boundaries can be done with tools like OpenTelemetry.

Scaling Databases For Global Serverless Applications

WorkshopFree

Ben Hagan

This workshop discusses the challenges Enterprises are facing when scaling the data tier to support multi-region deployments and serverless environments. Serverless edge functions and lightweight container orchestration enables applications and business logic to be easily deployed globally, often leaving the database as the latency and scaling bottleneck.
Join us to understand how PolyScale.ai solves these scaling challenges intelligently caching database data at the edge, without sacrificing transactionality or consistency. Get hands on with PolyScale for implementation, query observability and global latency testing with edge functions.

Ashley Narcisse

Apollo

This Talk discusses how to tool Apollo server with open tracing for observability. OpenTracing is a vendor-agnostic format that works well with distributed systems in microservices. It allows for converting GraphQL tracing data to a vendor-agnostic format and enriching information from GraphQL servers. If providers support OpenTracing, it can be easily integrated.

Comprehensive Observability via Distributed Tracing on Node.js8

Chinmay Gaikwad

Epsagon

Welcome to the session on comprehensive observability via distributed tracing on Node.js. We'll explore the challenges of microservices and troubleshoot distributed applications using an example. Correlation is the missing piece in troubleshooting distributed applications. Distributed tracing helps pinpoint issues that logging or metrics may miss, reducing mean time to resolution. It provides visualization of microservices architecture, actionable data, and enables code optimization.
